When you were kidnapped and stripped naked, the scientists inject your belly button with something, it becomes long and a solid wriggling piece of flesh, it looks like an Umbilical Cord, but it has a pointed tip at the end and it is wriggly and flexible, you see a piece of flesh wriggling in front of you, it is the same color as your skin it is also flexible and prehensile and it is naked and hairless, when a scientist pinches it you feel pain confirming it is your tail. Oh no you have a Tail coming out of your Belly Button, and it decides to fuck all of your private holes, you ever heard of your tail between your legs well in order to rape all of your holes it does just that, the first place it violates is your vagina, it feels so gross and wrong and disgusting yet oddly you feel bliss and pleasure from it as well, then the next place you feel it penetrate is your urethra and lastly it goes into your anus, you do not have any cum, urine or feces on your new tail. The Scientists are amazed and record their findings.
